The new organosulphur π-donor, 1,2-bis(thioxanthen-9-ylidene)ethene (4), which has high molecular symmetry, D2h, a minimized Coulombic repulsion of electrons in the doubly ionized state, and a planar cross-conjugated π-system, has been synthesized by a two-step sequence in an overall yield of 70%.
新型有机硫π-供体1,2-双(噻吨酮-9-亚乙基)乙烯(4)具有高分子对称性D 2 h,在双电离状态下电子的库仑排斥最小,且平面交叉通过两步序列合成了共轭π系统,总产率为70%。
